I have replaced engine assembly of my cultus 2007. Now car take jerk/jhtka on when rpm increase from 3000. I have changed all plugs and one plug cable but issue remains same.
Electrician are unable to resolve issue.
Fuel pump is working properly. Chechk engine lite become on and off sometime with jerk

There is sesnor after air filter box called Intake air Temperature sensor get the wiring checked one of the wires causes jerk issues and check light comes on goes.

Adjust your tp sensor position as it is getting tooo much air. Faced the same issue in my cultus

Wasn’t MAP(Manifold Absolute Pressure) sensor responsible for air monitoring?

I got the same issue after throttle servicing. In my case the tp sensor was the culprit bcz mechanic open it and did nt adjust it so when my car goes at 2500 rpm got a jerk very badly so i visited suzuki race course motors they solved it.
